This invention relatesto ladders and fori its object to prov-idea portable device for-supporting a ladder in an'ereot .or in` clined/ position.

is to-construot the laddersupporting device' be adjusted to suit uneven` ground. p

A further objectr of the present'invention -is to construct the device so-that it can readily be moved from place to place by one Aman' and can beusedwilth any ordinaryform of ladder. *f

rlhe present invention provides apparatus. 15 which is particularly useful 1n connection with fruit picking as thejapparatus constitutes means for supporting'a ladder for picking the :outside of a Itree without V,resting the. ladder against the tree whiohisthepresent trees. v

Further, apparatus constructed in accordance withA my invention also enables the lad# der to be supported ywithin the circumference ofthe tree again without damaging thev tree o r knocking downthe fruit. The apparatus can of course .be used for many other purposes than' fruit picking. Referring tothe drawings Figure 1r is a perspective' view of the.ap.

paratus inf its folded position.

In the construction `illustrated vthe apparatus comprises a frame lhaving block inembers 2 at the forward end kbetween which wheel l3 is mounted. 1

At the rearward end the frame terminates in handles 4 and vat the same end it is provided with adjustable legs 5. A These legs are :pivoted'to'the fra-me at 6 and an adjustment in the effective lengthof .each of Athese legs is permitted by providingrthem withaseries of holes 7 any oneof which4 can engagel with 4the pivot 6 carried bygtheiframezf usual practice and which is harmful to the 390,566, and in Great Biitam July 23, 1929.

l The'frame 1 is provided with a pair of` longitudinal members 8l which carry guide bars Seach guide ibar 9 also carrying a somen .i p s what similar bar 10 which is attached there- A further objeetof the present inventiony to on l.its ends Vbut-spaced `away therefrom along the greater part of its length. y The bars 9 and 10 are provided with holes 11'and lockingv pinssuch as 12. *.The upperend of each ofthe legs 5 projects between'the bars 9 and 10 and a pin such. as 12 caribe passed through the leg to lool: it in anadjustedy angular position :oritwo pins such yasA 12 may kbe .used `passing onv either side of the leg 5 so as toprevent it from rocking on its pivot 6.

-Atits forward end theframe is `further provided with legs y13 .which are pivoted at 14 to the frame and. these legs 13 are conneoted by V links 14a pivoted at 15 to the legs 13 and at 116 to operatinglevers 17. The

operating levers are pivoted at 18 to themembers .8. and they pass between the bars 9 and 10; and can be locked thereto 4by one or a pair of the locking pins 12 similar to thelegs. rlfhe effective length of `any of the legsr 5 or'13 can thus be adjusted by turning the leg on its pivotk and then locking it in ,an adjusted position while a further adjustment ispro-i vided for .the legs 5 by reason of theholes 7.

rllhemiddle part of the frame 1 is provided with pockets one 19 and the other 2O either of which can receive ythelower end of a ladder. The cross bar21 Vconnecting thefmembers 8 will form anabutment to prevent the lower y p .To the rear .of .the pocket 2O vis a footboard 30 andto the rear of the pocket 19r is ya footboard'31.

The upper end .of the frame 27 carries an extension frame 32 which is hinged at 33 to the frame 27.

lf a relatively short ladder is to be used it is placed in the pocket .2O and rests against the cross bar 34 of the frame 27 but if a long ladder such as 22 is to be used then the extension frame 32 is turnedupwardly about its pivot and the upper part of the ladder rests against a cross bar 35 on the extension frame 32.

The whole apparatus will fold into the position shown in Figure l by first removing the ladder then folding down the extension frame 32, after which the pins 26 are removed and the stays`2/l turned rearwardly on their pivots rlhe frame 27 Vcan now be turned downwardly on its hinge 28 and the legs 13 can be folded by operating the levers 17.

What I claim then is Y l. A ladder supporting device comprising a movable platform Aon' which the end ofV a ladder is adaptedl to rest, asingle supporting wheel at one end ofsaid platform, legs at both ends .of said platform adapted to form a support therefor when it is not being moved, a collapsible frame mounted on said platform for supporting a ladder intermediate its ends, collapsible supporting means for retaining said ladder support in an erected position and means for adjusting the position of said legs.

2. A ladder supporting device comprising a movable platform on which the end of a ladder'is adapted to rest, a single supporting wheel at one end of said platform, legs at both ends of said platform adapted to form a support therefor when it is not being moved, means for adjusting` the position of said legs, a collapsible frame mounted on said platform for supporting a ladder intermediate its ends, collapsible supporting means for retaining` saidladder support in an erected position and means for extending said ladder support.

3. A ladder supporting device comprising a movable platform on which the end of a ladder is adapted to rest, a single supporting wheel at oneend of said platform, legs adapted to support the platform when it is not being moved, means'for adjusting-the position of said legs, means for locking said legs in an adjusted position, a collapsible frame mounted on said platform forsupporting a ladder intermediate its ends, collapsible supporting means for retaining said ladder support in an erected position, means for extending said ladder support and said platform having a pocket for restraining the lower end of a ladder against movement.

4. A ladder supporting device y comprising a movable platform on which the end of a ladder is adapted to rest, a single supporting wheel at one end of said platform, legs at that end of the platform opposite to the end at which the supporting wheel is disposed, said legs having'a series ofjholes and port in an erected position and said platform having a pocket for restraining the lower end of a ladder against movement.

Y 5. A ladder supporting devieecomprising a movable platform on which the end of a ladder isadapted torest, a single supporting wheel' at one end of said platform, adjustable legs atV that end of the platformv opposite to the end at which the supporting wheel is disposed, pivotal legs at the same end of the platform as thesupporting wheel, means for adjusting said pivotal legs,-
